Abstract
In accordance with one implementation, a method for mitigating cache transfer time entails reading data into memory from at least two consecutive elliptical data tracks in a main store region of data storage and writing the data read from the at least two consecutive elliptical data tracks to a spiral data track within a cache storage region.
Claims20
A method comprising:
- reading data into volatile memory of a storage device;
- and
- writing the data to a spiral data track within a cache storage region of a magnetic disk.
A storage device comprising:
- a storage media including a cache storage region and a main store region;
- and
- a controller configured to control a transducer head to read data from at least two consecutive data tracks in the main store region and write the data read from the at least two consecutive data tracks to a spiral data track in the cache storage region.
A method comprising:
- determining a linear storage density capability of each of a plurality of transducer heads;
- identifying a subset of the transducer heads for which the determined linear storage density capability satisfies a predetermined threshold;
- assembling a storage device including at least one of the identified subset of transducer heads configured to write to a cache data region on a storage media.
